FREE NEET PG MCQ on 17 Nov 2016

Which of the following part of intestine has a feathery appearance on barium radiography?

A. Duodenum
B. Jejunum
C. Ileum
D. Cecum

TIPSImportant Question from NEET PG

Answer : B. Jejunum

Explanation :

The jejunum contains numerous mucosal folds(plicae circulares) which increase the surface area to aid with absorption of nutrients. These numerous mucosal folds produce the feathery appearance of the jejunum.
Although ileum is longer than jejunum, it has a thinner wall and has fewer mucosal folds. At the point of the ileocecal valve the inner lumen of the ileum is nearly smooth.
